Can anyone tell us about the pros and cons of wireless lavalier microphones

Now there are a lot of microphones on the market to choose from, all of which have their own characteristics, but if you want to choose a wireless microphone that suits you, you still have to be cautious.

1. The body is lightweight, only heavy, and the lavalier design makes it very convenient to carry out.

2. Three-level noise reduction adjustment, even in noisy environments, can be clear. Especially when shooting outdoors, the environment can be noisy, and the little bee can effectively reduce noise and record professional CD-level sound.

4G wireless transmission technology, stable connection within 80 meters.

4. Cost-effective, not as good as a thousand yuan to start one.

8 hours of ultra-long battery life, to ensure long-term use without pressure.

The advantage is wireless and small size, the disadvantage is that it is still too large and the transmission distance is too close!

There are many advantages, few disadvantages, and the distance is limited, which is about more than 100 meters.

First of all, the microphone capsule has a better timbre than the old one, but the clip at the back is not firmly stuck, and it is easy to fall off when hanging on the actor's body, and you may need to add a rope when performing a sketch. The elastic coefficient of the card is not very good, and if it is ruthless, it will relax, and it will never go back.

The well-known SHM5000 series also has a lot of flaws.

1.Fear of falling. If you're unlucky, the antenna in the back will crack with a drop, or the windshield will break.

2.The battery compartment is in poor contact. After a long time, if you pinch the upper and lower ends of the battery box by hand, you may have poor contact and make a "poof" sound.

Hope it helps.

1. OFF use the mobile phone to record the sparrows; on recording with a DSLR camera; The white metal is clamped and hung, mainly used to fix the microphone line; Open the metal clamp and put a button battery inside.

2. The fixed place of the lavalier can be clamped at the neckline for recording; Mi-cotton protective head; Microphone recording function; The universal MIC interface is suitable for most recording equipment.

This kind of microphone is connected to a small unlucky virtual wire transmitter, that is, the common thing on TV that hangs on the belt, and there is also a corresponding wireless receiver, to adjust the frequency of the transmitter and receiver to the same in order to effectively block it, just like a walkie-talkie, the frequency is inconsistent is not usable.

1. Turn off the recording with the mobile phone; on recording with a DSLR camera; The white metal is clamped and hung, mainly used to fix the microphone cable; Open the metal closed pants Zen clip hanging, and you can put a button battery inside. 2. The car dust collar clip is fixed, which can be clamped at the neckline for recording; Mi-cotton protective head; Microphone recording function; The universal MIC interface is suitable for most recording equipment.

Questions. How to connect the cool wireless lavalier microphone and mobile phone.

A wireless microphone, or wireless microphone, is an audio device that transmits sound signals, consisting of two parts: a transmitter and a receiver, and is usually called a wireless microphone system. The wireless microphone is composed of a number of pocket transmitters and a centralized receiver, each pocket transmitter has a different frequency of work, and the centralized receiver can simultaneously receive the voice signals of different working frequencies sent by the pocket transmitters of the hall.

This problem can not be explained clearly in two sentences, and the manufacturer's posture may be different or different. Simple: It is divided into potato shooting and receiving, receiving and equipment connection, and the manufacturer will have a connection line for distribution.

The transmitter is plugged in with a mark, and the transmitting and receiving channels are set to the same level. In this way, you can use the most basic, but if you want to use it better, you have to explore it slowly.

Friends, lavalier microphone is a wireless microphone, that is, the use of wireless lifting microphone, generally corresponding to the receiving system, must be correctly connected to the receiving system and amplifier and wide or sound can be used, some to modulate the reception, carefully adjust the corresponding to the cautious smile after the Wu can be.

How much is a wireless lavalier microphone**? Let's take a look today.

Wireless lavalier microphone** averageMore than 100 yuan to 3 or 400 yuanThe specific appearance depends on its brand, sound quality, radio noise reduction effect, size and other aspects. However, if it is a professional level, it is much more expensive, generally thousands or even thousands of yuan each.

Expand the knowledge: what parameters to pay attention to when buying a wireless lavalier microphone

1. Sensitivity

The higher the sensitivity, the stronger the lavalier microphone level gain output power and the clearer the sound quality.

2. Frequency response

Frequency response is a description of the resonance range of the audio bandwidth, and the limit of the frequency response that the human ear can receive is about 20Hz-20kHz. Under normal circumstances, the smoother and wider the frequency response of a good lavalier microphone, the better the vocal recording will be.

3. Letter-blind wide to-noise ratio

The signal-to-noise ratio refers to the ratio of signal output power to noise power, the larger the signal-to-noise ratio coefficient, the less noise and noise in the signal, and the clearer the sound quality. However, the signal-to-noise ratio of the lavalier microphone is generally not too high, and it is best to use a windproof sponge when shooting outdoors to reduce the pickup of ambient sound.

4. Directivity

Directivity is a general term for the sensitivity of microphones in different pickup directions, and there are two main types of polished lavalier microphones currently on the market: omnidirectional and cardioid. Omnidirectional pickup is relatively wide, and can pick up the sound source in a 360° range around the microphone, but the disadvantage is obvious, such as when you are in a noisy environment, the microphone will pick up the surrounding noise, which will affect the entire recording effect.

Cardioid directives are the best for picking up sources directly in front of the microphone, and are insensitive to sources on both sides and behind them, making them suitable for fixed-angle audio recording. When choosing, you can choose mainly according to your needs.

The above is today's sharing, I hope it can help you.

Lavalier wireless microphones can withstand high decibel sound pressure levels due to their small size, high sensitivity, low noise.

It is widely used in many fields without distortion. Such as: ENG (Electronic News Mu Fan Interview) and EFP (Electronic Live Program Production), Conference and Entertainment, TV Studio Production, Theater and Live Performance, etc.

A variety of options are also available to meet a variety of operational needs.

Lavalier microphones are divided into two types: wired lavalier microphones and wireless lavalier microphones, which are mostly wireless on the market. Wired lavalier microphones are mainly suitable for speeches, stage performances, television and radio use. The wireless lavalier microphone can be used for large-scale mobile conferences, recording pure Chang sound, public communication, outdoor speeches, lectures and other occasions.

The wireless lavalier microphone set consists of a miniature lavalier microphone and a bodypack transmitter.

and a receiver.

Small size and light weight. Microphone in the shape of a lavalier with rechargeable battery.

It weighs only 20g. It is the smallest and lightest product of its kind on the market. Products. There is no dress code for the user, and there is no sense of weight bearing for long periods of use. Easy to carry around, clean and easy to manage.

Green and eco-friendly. Ultra-low wireless transmission power, electromagnetic wave radiation is only 1 90 of ordinary mobile phones. Avoid high-frequency and high-power radio waves for long periods of time.

The damage to the human body in the environment is a veritable "green wireless microphone". The lithium battery power supply method that can be recharged is used to avoid disposable dry batteries.

Damage to the environment. At the same time, it can be used in a variety of occasions, which is very convenient and meets the needs of different consumers.

Some users have seen the host use the lavalier microphone to pronounce the sound very well in TV shows, but they themselves use this microphone to amplify the sound on the spot and do not achieve the sound effect that they imagined. This is usually because the microphone is worn too far away from the mouth, and the microphone will produce a physical phenomenon of feedback sound with the speaker during live amplification, and the volume cannot be arbitrarily raised, so the amplification effect is not good.

Since the lavalier microphone is worn on the chest and is far away from the mouth, the output volume will be greatly reduced, if the amplifier is used.

When the volume is turned up, it is easy to produce a feedback wheezing, which is a common problem encountered by ordinary microphone users. If you want to increase the volume of the microphone without producing a feedback sound, the only way is to use the principle of "the volume of the microphone is inversely proportional to the square of the distance of the sound source", and the distance between the microphone and the mouth can be shortened, and the sound of the microphone can be greatly improved.

What are the two types of wireless lavalier microphones? Let's take a look today.

Generally, there are two types of UHF (U-band) wireless systems with lavalier microphones and wireless digital lavalier microphones. At present, the wireless lavalier Mai Hong Chan Kefeng is a more mainstream lavalier microphone, the composition and technology of these two wireless lavalier microphones are different, in comparison, the U-segment signal frequency band is wider, usually more stable to use, the reception distance is farther, is a more mainstream choice. Cover the dust.

Expand on the facts: What is the difference between the two types?
